LoadVars.sendAndLoad() 325

Returns

A Boolean value; false if no parameters are specified, true otherwise.

Description

Method; sends the variables in the my_lv object to the specified URL. All enumerable variables in

my_lv are concatenated into a string in the application/x-www-form-urlencoded format by

default, and the string is posted to the URL using the HTTP

POST method. The MIME content

type sent in the HTTP request headers is the value of

my_lv.contentType or the default

application/x-www-form-urlencoded. The POST method is used unless GET is specified.

You must specify the

target parameter to ensure that the script or application at the specified

URL will be executed. If you omit the

target parameter, the function will return true, but the

script or application will not be executed.

The

send() method is useful if you want the server response to:

• replace the SWF content (use "_self" as the target parameter);

• appear in a new window (use "_blank" as the target parameter);

• appear in the parent or top-level frame (use "_parent" or "_top" as the target parameter);

• appear in a named frame (use the frame’s name as a string for the target parameter).

A successful

send() method call will always open a new browser window or replace content in an

existing window or frame. If you would rather send information to a server and continue playing

your SWF file without opening a new window or replacing content in a window or frame, then

you should use

LoadVars.sendAndLoad().

This method is similar to

XML.send().

Example

The following example copies two values from text fields and sends the data to a CFM script,

which is used to handle the information. For example, the script might check if the user got a

high score and then insert that data into a database table.

var my_lv:LoadVars = new LoadVars();

my_lv.playerName = playerName_txt.text;

my_lv.playerScore = playerScore_txt.text;

my_lv.send("setscore.cfm", "_blank", "POST");
